I'm not looking to go forced-induction, but are there any advantages to upgrading your fuel injectors? I have about 25k miles. I'm looking for ways to improve my gas mileage. []

Bigger injectors will usually decrease driveability and millage if anything from what I've heard.

A bigger injector would need a new calibration to be used effectively

For instance, on hot re-starts you would likely get a big RPM flare up because the larger injectors leak more fuel.

If you really want to experiement, try getting a really good set of matched stock-rate injectors from someplace like www.rceng.com

Changing injectors probablly wont help mileage.... you only change injectors when you need more fuel.
